What is the Lewis structure for carbon anion?

The Lewis structure for the carbon anion (C⁻) features a carbon atom with a total of four valence electrons, plus one additional electron due to the negative charge, giving it five valence electrons in total. In the structure, the carbon atom is represented with five dots around it, indicating its valence electrons. There are no bonds depicted in this anion, as it is typically shown in its isolated form. The overall structure reflects the negative charge by indicating the extra electron.
